# Testing RadioGroup

## Test utils

`@react-spectrum/test-utils` offers common radio group interaction testing utilities. Install it with your preferred package manager.

<InstallCommand pkg="@react-spectrum/test-utils" flags="--dev" />

<InlineAlert variant="notice">
  <Heading>Requirements</Heading>
  <Content>Please note that this library uses [@testing-library/react@16](https://www.npmjs.com/package/@testing-library/react) and [@testing-library/user-event@14](https://www.npmjs.com/package/@testing-library/user-event). This means that you need to be on React 18+ in order for these utilities to work.</Content>

Initialize a `User` object at the top of your test file, and use it to create a `RadioGroup` pattern tester in your test cases. The tester has methods that you can call within your test to query for specific subcomponents or simulate common interactions.

```ts
// RadioGroup.test.ts
import {render} from '@testing-library/react';
import {User} from '@react-spectrum/test-utils';

let testUtilUser = new User({
  interactionType: 'mouse',
  advanceTimer: jest.advanceTimersByTime
});
// ...

it('RadioGroup can switch the selected radio', async function () {
  // Render your test component/app and initialize the radiogroup tester
  let {getByRole} = render(
    <RadioGroup>
      ...
    </RadioGroup>
  );

  let radioGroupTester = testUtilUser.createTester('RadioGroup', {root: getByRole('radiogroup')});
  let radios = radioGroupTester.radios;
  expect(radioGroupTester.selectedRadio).toBeFalsy();

  await radioGroupTester.triggerRadio({radio: radios[0]});
  expect(radioGroupTester.selectedRadio).toBe(radios[0]);

  await radioGroupTester.triggerRadio({radio: radios[1]});
  expect(radioGroupTester.selectedRadio).toBe(radios[1]);
});
```
